从中我们可以看到: 当我们spawn一个进程的时候,Python multiprocessing实际还额外创建了一个resource_tracker进程,来追踪记录子进程的资源使用情况。 实际上我们的子进程执行的程序是python -c 'from multiprocessing.spawn import spawn_main; spawn_main(tracker_fd=4, pipe_handle=6)' --multiprocessing-fork,它可以...
对于python的派生模式还细分为fork和spawn两种方式。在fork模式和无相关模式下,因为python本身提供了内存垃圾回收的机制,在代码中一旦创建或者关联共享内存,会默认启动一个resource_tracker的跟踪子进程。如图所示,在fork模式下,每个进程都附加一个跟踪子进程。

The bug is about resource tracker destroys shared memory segments when other processes should still have valid access. So take care if you use it in your code. PyTorch 也有自带的多进程 torch.multiprocessing How to share a list of tensors in PyTorch multiprocessing? rozyang 的回答 ,非常简单,...
Python 自带的多进程库 multiprocessing可实现多进程。我想用这些短例子示范如何优雅地用多线程。中文网络上,有些人只是翻译了旧版的Python官网的多进程文档。而我这篇文章会额外讲一讲下方加粗部分的内容。 创建进程 Process,fork 直接继承资源,所以初始化更快,spawn 只继承必要的资源,所以更省内存,「程序的入口」 ...
